This idea was lingering on my list for so long that a service that didn’t exist back then has now seen an explosion of these services mostly due to the pandemic and how easy it is to create one. Almost all grocery stores do it nowadays, if they don’t you can always use a service like task rabbit to do it for you.
How to make a different grocery delivery services
However, there seem to be some caveats for these services, with the exception of task rabbit they seem to only work for one store.
Perhaps a way to have a unique offering for your app, it could offer delivery service from multiple stores. The logistics of that can be tricky though, especially with perishable goods.
Integrate this idea with previous grocery & food related idea.
You see that a store has good deal in your area with your crowdsourced grocery app (Idea #32), add a button to do your grocery online at that store and have them delivered at your place.
Need some ingredients for your meal plan (Idea #37 & #38) or for you recipe from your favorite foodie social network (Idea #40)? Have these ingredients automatically added to your grocery list via your app before making an order on your grocery delivery service.
If you can beat them, join them.
If the logistics of such a service is too daunting, our previous food related idea could be linked with pre existing grocery delivery services. You have to look up for a service that has an api. Perhaps strike a deal with them so your customer get a rebate for those service or you get an affiliate commission for those who register to those.
